We have compared our lyophilized proteins incubated at 37 °C for 3 days with those stored at -80 °C and found no difference in their bioactivity (EC50) using our standard assays. Therefore, as part of our commitment to the environment and supporting more eco-friendly packaging, we send all of our lyophilized proteins at room temperature, avoiding the need for dry ice, ice packs and gels.
